Product details

Overview

2SC4614S-AN from onsemi is an NPN bipolar junction transistor designed for high-voltage switching applications, featuring V_CEO = 160 V, I_C = 1.5 A continuous, f_T = 120 MHz, low V_CE(sat) of 130 mV at I_C = 500 mA / I_B = 50 mA, and SC-71 (NMP) surface-mount package. It is used in DC-DC converters, relay drivers, and industrial power control circuits.

For engineers reviewing the 2SC4614S-AN datasheet, pinout, applications, or equivalent options, key selection criteria include breakdown voltage margin, saturation voltage under specified drive conditions, hFE rank classification (S-grade: 140–280), thermal derating above 25°C, and tape-and-reel packaging compatibility with automated SMT assembly.

Technical Context

The 2SC4614S-AN employs MBIT process technology to achieve high breakdown voltage and robust current handling while maintaining fast switching performance. Its V_(BR)CBO = –180 V and V_(BR)CEO = –160 V support operation in high-side switch configurations up to 100 V rail systems.

With t_on = 40 ns, t_stg = 1.2 μs, and t_f = 80 ns under defined test conditions, it delivers predictable turn-off behavior suitable for pulse-width modulated loads. The device's hFE is binned by rank (S/T), and its Cob = 14 pF at V_CB = –10 V enables stable high-frequency gain response.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	160 V - Supports reliable operation in 100 V DC bus switching without avalanche stress
I_C	1.5 A continuous - Enables direct drive of medium-power solenoids or MOSFET gate charge pumps
V_CE(sat)	130 mV @ I_C=500 mA/I_B=50 mA - Minimizes conduction loss in saturated-switch mode
f_T	120 MHz - Allows stable amplification or switching up to ~10–15 MHz practical bandwidth
hFE (Rank S)	140–280 @ V_CE=–5 V, I_C=–100 mA - Ensures consistent base drive requirements across production lots
C_ob	14 pF @ V_CB=–10 V - Limits Miller capacitance impact on high-speed switching transitions
P_C	1 W @ T_A=25°C - Requires thermal pad or copper pour for >500 mA sustained duty

Pinout & Package

Package: SC-71 (JEITA/ JEDEC standard), also designated NMP(Taping); molded plastic surface-mount package with gull-wing leads, 0.275 g mass, 2.54 mm lead pitch, and 6.9 mm × 3.0 mm footprint.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink node; connects to ground or low-side return path in common-emitter configuration
2	Collector	High-voltage output node; ties to load or positive rail in low-side switch topology
3	Base	Control input; requires current-limited drive (e.g., 50 mA typical for 500 mA collector current)

Key Features

Feature	Design Value
MBIT process technology	Enables simultaneous optimization of breakdown voltage, current gain, and switching speed
Low V_CE(sat)	130 mV ensures <130 mW conduction loss at 1 A, reducing thermal load in compact layouts
Rank-binned hFE (S-grade)	140–280 range simplifies base resistor selection and improves batch-to-batch consistency
SC-71 package	Standardized JEITA/ JEDEC footprint supports automated placement and reflow compatibility
High f_T / low C_ob ratio	120 MHz gain-bandwidth with only 14 pF output capacitance enables clean edge fidelity

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC4614T-AN	Same package and absolute ratings, but hFE rank T (200–400) - higher gain, tighter distribution	Preferred where lower base drive current or improved gain stability across temperature is required	Select 2SC4614T-AN when designing for minimal base current sourcing capability or tighter hFE tolerance
MJD127G	V_CEO = 100 V (lower), I_C = 2 A, TO-252 package - larger footprint, higher current, reduced voltage margin	Suitable for lower-voltage (<80 V) industrial controls where PCB space allows DPAK	Choose MJD127G only if system voltage remains ≤80 V and thermal management supports TO-252 mounting

Compared with 2SC4614T-AN, the 2SC4614S-AN offers lower guaranteed hFE but tighter binning for predictable base drive design; versus MJD127G, it trades current capacity for superior voltage headroom and smaller SC-71 footprint-critical for space-constrained 100 V rail applications.

FAQ

What is the maximum continuous collector current rating for the 2SC4614S-AN?

The 2SC4614S-AN has a maximum continuous collector current I_C of 1.5 A at T_A = 25°C. Derating is required above this temperature: at 75°C ambient, maximum I_C drops to approximately 1.0 A per the PC–Ta curve. This rating assumes adequate PCB copper area for heat dissipation and applies only in common-emitter configuration with base properly biased.

Does the 2SC4614S-AN have a Pb-free and RoHS-compliant construction?

Yes, the 2SC4614S-AN is Pb-free and RoHS-compliant, as confirmed in the ordering information section of the official datasheet (Ordering Number EN3578A). The "-AN" suffix denotes lead-free termination and green molding compound, meeting JEDEC J-STD-609 Category 1a requirements for homogeneous material compliance.

How does the hFE rank "S" differ from "T" in the 2SC4614S-AN and 2SC4614T-AN variants?

The "S" rank in 2SC4614S-AN specifies hFE between 140 and 280 at V_CE = –5 V and I_C = –100 mA, while "T" rank (2SC4614T-AN) guarantees 200–400 under identical conditions. Both share identical absolute maximum ratings and package, but S-grade provides tighter upper bound control for designs sensitive to excessive gain variation.

Can the 2SC4614S-AN be used in linear amplifier applications?

The 2SC4614S-AN is optimized for switching-not linear amplification. Its f_T = 120 MHz and Cob = 14 pF support broadband switching, but lack of specified linearity parameters (e.g., THD, NF, or SOA curves beyond DC) and absence of small-signal AC characteristics make it unsuitable for precision analog amplification. Use only in saturated or cutoff regions.

What is the recommended PCB land pattern for the SC-71 (NMP) package of the 2SC4614S-AN?

The official outline drawing (No.3578-6/7) specifies a 2.54 mm lead pitch and 0.6 mm lead width. Recommended land pattern uses 1.0 mm × 1.45 mm pads for pins 1 and 2, 1.0 mm × 1.05 mm for pin 3, with 0.45 mm solder mask opening and 0.2 mm solder paste stencil aperture-matching JEITA ED-7301B guidelines for SC-71 reliability and coplanarity control.
